Stability and Performance Analysis of Control Systems Subject to Bursts of Deadline Misses

Control systems are by design robust to various disturbances, ranging from noise to unmodelled dynamics. Recent work on the weakly hard model---applied to controllers---has shown that control tasks can also be inherently robust to deadline misses. However, existing exact analyses are limited to the stability of the closed-loop system. In this paper we show that stability is important but cannot be

Data-center infrastructure and energy gentrification : perspectives from Sweden

Which societal functions should be prioritized when the electricity grid reaches its maximum capacity? By using Sweden as an example, this policy brief discusses the societal negotia- tions that arise around capacity deficits of the electricity grid. By introducing the term energy gentrification, we aim to highlight the potential dangers of failing to recognize that energy also constitutes a socie

Nine residues in HLA-DQ molecules determine with susceptibility and resistance to type 1 diabetes among young children in Sweden

HLA-DQ molecules account over 50% genetic risk of type 1 diabetes (T1D), but little is known about associated residues. Through next generation targeted sequencing technology and deep learning of DQ residue sequences, the aim was to uncover critical residues and their motifs associated with T1D. Our analysis uncovered (αa1, α44, α157, α196) and (β9, β30, β57, β70, β135) on the HLA-DQ molecule. The

Beyond Blame : What Investigations of Intelligence Failures can Learn From Aviation Safety

Investigations into intelligence failures are frequently conducted by multiple parties in parallel, and in several important cases, their conclusions have been controversial. In addition, investigations into minor incidents, such as mishandling of sensitive information or equipment, tradecraft errors, or similar events where no major consequences have been detected, tend to be handled internally b

On the governmentalization of sustainability: the case of flood risk mitigation in Sweden

Contemporary society is confronted with numerous sustainability challenges. Some are new, others have been around since time immemorial, but none have been governed on the societal level since their emergence. Despite an abundant literature that addresses the governing of a range of such sustainability challenges, the processes through which they become something governable in the first place have

Green Steel Tracker

The Green Steel Tracker aims to support decision makers in policy and industry, academia as well as civil society, by tracking public announcements of low-carbon investments in the steel industry and presenting them transparently in one place.

Flexible Rigidity and Caring Distance. : How discretion works in compulsory care.

The aim of this article was to develop the understanding of discretion in compulsory care for youth and the influence of emotional aspects in developing a collective discretionary practice. The empirical material consists of group interviews with staff at these institutions. The theoretical concepts of emotional labour and emotional energy are used to understand discretion and face-to-face interac

Pharmaceutical industry self-regulation and non-transparency : country and company level analysis of payments to healthcare professionals in seven European countries

The European pharmaceutical industry uses the alleged efficacy of self-regulation to question the need for transparency laws similar to the US Physician Payment Sunshine Act. We conducted a comparative analysis of 20 large companies’ payment disclosures in seven European countries in 2017–2019. The data was extracted as part of eurosfordocs.eu, a novel transparency project that scrapes and integra

Perovskite solar cell performance assessment

Astounding progress in achieved power conversion efficiencies of solar cells based on metal-halide perovskite semiconductors has been achieved. Viable assessment of the long-term device performance is, therefore, now the most critical aspect to reliably predict device's long-term performance. Standard testing protocols to enable cross-laboratory comparison need to be established and adopted. Apart

Improved Electrical Performance of Perovskite Photovoltaic Mini-Modules through Controlled PbI2 Formation Using Nanosecond Laser Pulses for P3 Patterning

The upscaling of perovskite solar cells to modules requires the patterning of the layer stack in individual cells that are monolithically interconnected in series. This interconnection scheme is composed of three lines, P1–P3, which are scribed using a pulsed laser beam. The P3 scribe is intended to isolate the back contact layer of neighboring cells, but is often affected by undesired effects suc

Optical Fingerprints of Polynuclear Complexes in Lead Halide Perovskite Precursor Solutions

Solvent-solute interactions in precursor solutions of lead halide perovskites (LHPs) critically impact the quality of solution-processed materials, as they lead to the formation of a variety of poly-iodoplumbates that act as building blocks for LHPs. The formation of [PbI2+n]n- complexes is often expected in diluted solutions, while coordination occurring at high concentrations is not yet well und
